Technicians loading/unloading cargo/freight from the supply plane at Concordia. French;in blue) and Italian;in red) technicians help unload the Basler - Douglas DC3, which delivers scientific and/or technical equipment to the Concordia station several times a month during the summer. It takes a team of 6 to 20 people just 3 minutes to unload the 2 tonnes of cargo, reload the same amount of equipment into the plane and refuel the aircraft with kerosene. As soon as these operations are completed, the plane is ready to leave again. Concordia Antarctic Research Station, Dome C plateau, East Antarctica.

Snowdrift in front of a tent. A dormitory tent dating from the 1990s and still in use. It is heated by a small oil-fired stove. Every obstacle in the wind creates snowdrifts, which have to be removed periodically to prevent burial. Concordia Antarctic Research Station, Dome C plateau, East Antarctica.

Frozen ground of Dome C, and sastrugis. Sastrugis are wind-blown snow formations. The wind is not extremely strong in these high-altitude locations. Concordia Station, Antarctic

A technician goes into a raised square building on an orange metal structure. An Italian technician specialising in radio and telecommunications goes into the shelter that houses the VSAT antenna, the device that connects the station to the Internet by satellite. This is the station's only link with the outside world. Most of the buildings are elevated to prevent the formation of snowdrifts caused by wind-blown snow. Concordia Antarctic Research Station, Dome C plateau, East Antarctica.

The two towers of the Concordia station, with the French, Italian and European flags flying in the wind, under a blue sky veiled with cirrus clouds aligned in the direction of the wind. The two towers are linked by a tunnel. They are permanently heated to 20°C by the diesel engine that generates the station's electricity. The left tower is the "quiet tower", housing the hospital, bedrooms;34 beds) and offices. The right tower is the "noisy tower": it houses a small workshop, the emergency generator, the waste room, the technical office, the video room, the living room, the kitchens and the refectory. The two towers are about ten meters apart to prevent the risk of fire spreading. Fire is an Antarctic expeditionary's worst nightmare; the French have a very bad experience of it.
